 \hline\hline \end{tabular*} {\centering \caption*{\begin{footnotesize} This table provides information by cohort on the 45 state-level events used in the event-study analysis. The 45 events are defined as per state minimum wage changes. Availability of data and variation across county/commuting zone pairs dictate which events are actually used in different specifications. The first column reports the number of events in that cohort/year. The second column gives the length of the post-period for that cohort in years. Post-periods are a maximum of 6 years unless interrupted by a federal MW increase year or end-of-sample. The third column reports number of states that serve as clean controls for the cohort - a clean control needs to have no state MW increase in the three years before the cohort year, and also no state MW increase in the relevant post-period. Finally, the last column reports the average log MW increase (average of the difference between log MW in the last year of the post-period and the log MW in year \textit{t-1}, where \textit{t} is the event year) across all events in a cohort. The last row gives the total number of events and means \textit{by event} (not by cohort) of post-period length, clean control states, and log MW increase. \end{footnotesize}}} \end{table}
